<![CDATA[Artificial reefs are made to act as temporary substitutes for small areas of damaged original reef. The structures attract fish and other marine organisms, which can eventually be exploited (e.g. for human food), so it is expected that they will form the basis around which natural reefs can grow and recover. The purpose of this study is to document recruitment of organisms onto the artificial structures, evaluate the effectiveness of the structures in terms of shape and recruitment potential, and use the recruitment information to show which species occur in the surrounding reefs. This research was conducted from May-July 2010 in north Bali, in the Village District Gerokgak Patas, Kampung Baru Village in Buleleng District, and Penuktukan Village, Kecematan Tejakula. The research method used was a visual census method to determine the number of fish species and fish abundance on artificial reefs at three different locations. Three replications were performed at each location. 2481 individuals from 18 families (38 species) of reef fish were observed. The area with the greatest abundance of fish and the highest number of fish species was in Kampung Baru, with 1170 individuals from 21 species of fish. Dominant reef fish species were Plotosus lineatus (Cat Fish) - 510 individuals, Pomacentrus auriventris (Goldbelly damsel)- 256 individuals, Dascyllus trimaculatus (Three spot damsel) - 335 individuals, Pseudanthias squamipinnis (Lyretail Anthias) - 320 individuals. A Sorensen analysis showed that reef fish communities on the artificial reefs in the form of 'hexadomes' were not derived from the surrounding reefs.]]>

<![CDATA[On August 21, 2009 an offshore oil rigs located in Block West Australia territorial was exploded. About 500.000 liters/day of crude oil was spill out to the Timar Sea. To detect the oil spreading, this study used MODIS satellite data from 21 August 2009 until 15 March 2011. Besides that, data of wind speed and wind direction, coordinate of pollutant point sources, and Exclusive Economic Zone (EEZ) line are also used to know the covering area of the oil was entered into Indonesian territorial. The oil was classified by visual interpretation methods, these are: dark spot detection, feature extraction and classification. As the result, oil spill covered area increased since August to September 2009. Oil spill on the sea surface then decreased drastically until November 2009. This was due to dispersant spraying which made the oil settled down. But, when a tropical cyclone occurred in December 2009 and January 2010, the settled oil appear again in sea surface but it spread out in various location. This study shows that MODIS data can be used to monitor spreading of oil spill since no cloud cover. The maximum oil covered area was occurred on 24 September 2009 about 7,996-40 km2]]>

<![CDATA[Indonesia as an archipelagic country has the potentiality of a huge fishery resources and high biodiversity. Fishresources in the waters can be estimated by knowing the content of the primary production (PP) of these waters.The aim of the research are to estimate the variability of environment parameter (SST and Chl-a concentration)and to estimate of PP and fish production (FP), derived from satellite around Indonesia Archipelago.The research was conducted in nine of Indonesia Fisheries Management Area from 2004 to 2006. The PPwas calculated by Vertically Generalized Production Model (VGPM), which was introduced by Behrenfeld andFalkowski (1997a). The model introduced by Pauly and Christensen (1995) calculated the FP. The estimationof FP from model was compared to the FP data from the Department of Marine and Fisheries Resources ofIndonesia.In the territorial waters of Indonesia Archipelago the highest variations of average SST and Chl-a was estimatedat Arafuru Sea, whereas the lowest variation was estimated at Sulawesi Sea and Pacific Ocean. The total annualfish production from the model showed the highest and the lowest values were estimated at Indian Ocean(1,614,135.44 tons) and Malacca Strait (268,305.64 tons), respectively. On the other hand, the total annualfish production from Department of Marine and Fisheries Resources of Indonesia showed the highest and thelowest values were estimated at Java Sea (850,151 tons) and Banda Sea (198,078 tons), respectively. The highestcorrelation between fish production from satellite data and the data from Department of Marine and FisheriesResources of Indonesia was found at Arafuru Sea with R = 0.97. The nine fisheries areas of Indonesia during2004 to 2006 were categorized as fully until over exploited fishing zone.]]>

<![CDATA[The study was conducted in order to assess the damages of forest resources due to mining activities. The method which use in this article is the nonnative legal research concerning with the legislation approach, the case study approach and the library approach. The result of this study indicated that be damage of forestry by mining activities threatens convenient ecosystem of Indonesia seriously. The study materials show obtained that the original forest area in Indonesia were 144 million hectares, but have been systematically shrinkaged that remained only 130 million hectares now, even though the 42 million hectares were completely without vegetation. Primary forest left only 43 million hectares from forest encroachment and as rate currently reaches 1.1 million hectares per year. The result study showed that according with the governor's report in 10 provincies throughout Indonesia the forest destructions are dominated by mining activities. The facts in the fields also showed that the mining locations clearly faced visiable forests of Indonesia destroyed by quarrying, waste disposal and mining operations support activities. The governmental policies to allow mining activities in protective and conservation forest will destruct of forest resources. To address the threat of forest destruction it is suggested that the Government shall revitalize the implementation of provisions with Act No. 41 of 1999, the Act No. 19 of 2004 and the Presidential Decree. No. 41 of 2004, the Cabinet Act 24 of 2010 and the Presidential Decree No. 28 of 2011 concerning with the preservation of forest resources are still maintained.]]>
